ZINC-SUPPORT FOR BATTERIES.

SPECIFICATION forming part of Letters Patent No. 647,536, dated April17, 1900.

Application filed April 1 7, 1899.

T0 aZZ whom, it may concern:

Be it known that I, SAMUEL E. SMITH, a citizen of the United States,residing at Beloit, in the county of Rock and State of Wisconsin, haveinvented certain new and useful Improvements in Zinc-Supports forBatteries, of which the following is a specification.

The object of this invention is to construct a support for the zinc of abattery which is made reversible, so that a single zinc or two zines canbe supported, and in which the hinding-posts form the connection betweenthe support and zinc.

In the accompanying drawings, Figure l is an isometrical representationof my improved zinc-support in the position it occupies when a singlezinc is used. Fig. 2 is a View of the zinc-support in the position itoccupies when two zines are used. Fig. 3 is a section of a jar, showingmy holders in connection therewith and in which a single zinc is used.Fig. 4 is a similar view in which two zincs are used. Fig. 5 is anisometrical representation of anew zinc. Fig. 6 is an isometricalrepresentation of a partially-consumed zinc.

My improved holder consists of a bar portion 1, having a central opening2 and end extensions 3, which are preferably bifurcated or forked inorder to lend lightness to the bar and also to provide a broadsupporting-surface. The said extensions 3 are each provided with twosupporting-surfaces, those on one face or edge being offset, so thatsuch offset faces or edges will provide a supporting-surface and holdthe bar 1 on a different hori zontal plane from those on the oppositeedge. Near the extreme end of each extension, directly in rear of suchsupporting-surfaces, I provide upper and lower shoulders 4 4, for apurpose presently to appear.

When a single zinc is employed, the parts will appear as shown at Fig.3. A zinc connection 5, having a screw-thread extending throughout itslength and a central screwthreaded opening in one. end, is clamped tothe bar portion of the support by the screwthreaded extension 6 of thebinding-post 7, which latter passes through the opening 2 in the barportion of the support into the screw threaded end of the connection.

Serial No. 713,815. (No model.)

A new zinc 8, such as is shown at Fig 5,11av

ing a screw-threaded cen tral opening,is turned in connection with theconnector until the lower end of the connector is flush with the underside of the Zinc, which will hold the zinc the proper distance below thefluid-level in the jar, as shown by the dotted line. 9.

When the battery is'placed in circuit, the zinc will be consumed untilit appears as shown at Fig. 6 or the dotted lines in Fig. 8. When asingle zinc is used, the bar portion 1 is on a lower horizontal planethan the ends 3, and the shoulders 4 prevent the holder from becomingdisplaced in its connection with the ar. When two zines are used, theholder is turned over, so that the bar portion-will be in a higherhorizontal plane than the end portions, as shown at Fig. 4. In order tosupport the top zinc the same level below the fluid, it will benecessary to lower the zinc in its connection with the connector 5, anda second connector 10 is turned into the lower portion of the new zinc,so that a portion of its length will extend below the zinc onto thisprotruding portion. The old or partly-consumed zinc 11 is turned, whenthe parts will appear as shown at Fig. 4, and when this battery is inuse the lower zinc will be entirely consumed and the top zinc will bepartly consumed, until it appears as shown at Fig. 6.

I claim as my invention 7 l. A reversible battery-zinc supportcomprising a bar portion having end extensions provided with shouldersupon the upper and lower edges thereof near the extremities of the bar,said extensions providing two pairs of supporting-surfaces for the bar,one pair of such. supporting-surfaces being on a plane substantially inline with the bar and the other pair being on a diiferent horizontalplane, for the purpose specified, and means for attaching thebattery-zinc to the bar.

2. A reversible battery-zinc support comprising a bar portion havingbifurcated end extensions provided with shoulders upon the upper andlower edges thereof near the extremities of the bar, said end extensionsproviding two pairs of supporting-surfaces for the bar, one pair beingon a different horiin line with the bar and the other pair being on adififerent plane from the bar, and means :0 for attaching the zinc tothe bar, substantially as described.
